I have a Ubuntu server (without GUI) and ps3mediaserver up and running, my PS3 can connect and play movies, but not my Samsung 7070.When i install the windows version of ps3mediaserver it works on my TV as well, so it should be able to get up and running on my linux-box as well.This is the error-message i get from the debug-log when i connect with the TV and try to play something, same result with all movie types:

When you say it works well with your set, do you mean your able to connect and browse files ? Or the next step of playback of e.g xvids, mkv's etc is all working also ? To confirm that is using PMS directly connected to the 7070 not via a PS3 ?
